.tion of the iron, the recess in the base of the iron,`forming the chambers and 16, is tapered at its forward end in correspondence with the tapering of the casing 8.

The heating member, as said,fcomprises vamong other reasons, to increase the ca- -fflikewiseis tapered to correspondk with'thel tapering recess 1n which it is located, and

pacity of the chambers 15, 16, and to facilitate the approach of the air to the jet openings presently to be described. f The burner in 4this manner sufficient space is `provided for' proper combustion and consequent heating'of the toe, thus overcoming a defect in the constructions of the art. The burner may be provided with the usual air 'mixing tube,

" not shown..

2o base, the b urner is provided with ,horiz-one" 'j said portions 23, `24 of the top surface of' Further toinsure efficient heating ofthe tally directed perforatioiis 22 foi-medin each of its sides, as shown, about midway thereof, and slightly 'above the top surface yof the base. Said top surface, while generally horie zontal,'is upwardly inclined at its outer por`v tions, see Fig. 3, being divided b'ysaid re- Y cess intovtwo portions 23 and 24. It will be seen that by reason of this construction the Haines of the burner are projected nearly i horizontally at a slight distance above' the the base, and at their ends will curl vup'- wardly and thus the heated products of f combustion will be used tothe best advan-y sloping .upwardly atits outward portions, a

27." Preferably, andas shown, the bailley comprises a bottom 28, vertical ysides 29,

and rear wall 30, and a top plate 31, bev-` tween which plate and outwardly extending ianges 33 of vthe walls 29 is preferably placed ak sheet 34 of insulating material, as asbestos. The'forward portion 36 of the bottom 28 is inclined upwardly to facilitate the disposition of the heated products of combustion, which, passing upwardly along said inclined portion and also in the space between the sides 29 of the baffle and the `walls of the casing, seej Fig. 3, escape of the iron from becoming too hot. It willA y through the vents 38 formed in vthe upper Y sides of the casing.

The-baiie thus forms an insulating chamber,` preventing the top be noted, see Fig.:3, that thebottom of the baffle thus constitutes the topof a chamber,

in Which'the burner is partly located, and 6o,

the iron.'l f

of` the invention relates4 chamber above the burner formed in part by the bottom ofthe baflle, As shown, see

Y 11, these front and rear ports being in coma burner 14, preferably of cylindrical shape,

munication with the said chamber -and with each other.V The movement of the iron back and forth will cause a sufficient draft to keep the iron at a proper temperature and properly to regulate the escape of the heated lproducts of combustion,

It will be seen that a sad iron constructed in accordance with the invention carries out the obj ects of the invention, while possessing v other advantages, whichk will be apparent to `inay be carried into effect, as many changes may be made in the details without departing from the main principles of the invention o r sacrilicing its chief advantages.

11. A sad iron including in combination, a hollow body, the base thereof having a tapering recess, a tapering burner arranged in said recess, vhorizontally directed perforations formed in said burner above the top surface of said base, and air ports in said base communicating with said recess.

12. A sad iron including in combination, a hollow body, the base thereof having a recess therein, a burner arranged in said recess and dividing the same into chambers,

and the roof of each said chamber having its edge adjacent the burner spaced apart therefrom.

13. A sad'iron including in combination, a hollow body, the base thereof having a recess therein, said recess having overhanging ledges, and burner arranged in said recess and spaced apart from said ledges and dividing said recess into chambers.

14. A sad iron including incombination, a hollow body, the base thereof having a recess therein, said recess having overhang- `face of said base.

Y recess andy spaced apartfrom said ledges and dividing said recess into chambers, and horizontally directed perforations formed in ,each side of'said' burner above the top surface of said base, and' air portsinjsaid base communicating with said recess. s

16.v A sad iron including in combination,

a hollow body, a burner arranged on said base longitudinally and mid-way thereof, horizontally directed perforations formed in each side of said burner, and a pair of air supply chambers arranged one on each side `of `said burner and beneath said perfora-y tions. n y
